Hello.

 

I have a network managed with OC200 and an ER8411 router. Both devices are on the latest software version.

 

I have several wired networks configured using vlan interfaces and until now, when I created a new network and activated the dhcp server, it immediately worked.

 

Now I have created two new networks, and the devices do not receive IPs via dhcp.

 

Has anything changed regarding this?

  @NovaSistemas 

 

what happens when you set the gateway ip manually on the DHCP server ?

 Hi @NovaSistemas 

 

What IP address will the devices in the new VLAN11 get? IP address in default VLAN, or invalid IP address?

 

Please also let us know the topology of your network, and how does the client in VLAN 11 connect to the network

 Hi.

I'll provide more information.

 

These are the network devices.

 

 

These are the networks. All the networks that are not marked in red existed before the update, and are functional. After the update, I have created the networks marked in red, and the devices connected to ports associated with that profile do not receive IP from the dhcp server. If I configure the device with an IP from that range, it cannot communicate with the router either. It seems that there is no communication between that vlan and the router.

 

Although there are ACLs at the gateway level, none of them should affect this. As a test, I have disabled all denny ACLs and it still does not work.

I had also tried it and it had no effect.
